Data Set Entry

A major strength of the TI-83 graphing calculator is the ability to work with a data set. You can enter, plot, and perform a variety of statistical analyses on the data set. Here we indicate how to enter a data set.

Press to access the statistics editor. Press to select 1:Edit... This takes you to the data editor. The editor is a spreadsheet arranged in columns. The TI-83 refers to a column as a list. Hence, the spreadsheet contains L1 (list 1), L2 (list 2), etc. If there are old data in a column, use the thumb pad arrows to highlight a list header (such as L1), then press CLEAR ENTER to clear the column.
